When fitting our equation to the histograms created by the
computer-generated data, Origin allows us to either fix or let the four variables
(w, A, y0, and xc) vary. Because of this, we did three different sets of analysis
on the six sets of data. The first followed Chorng's experiment, holding y0 fixed
at zero and allowing w, A and xc to vary. We then let everything vary and finally
just allowed w to vary, keeping A, y0 and xc fixed at 6.25 x 10-8, 0
and 0 respectively. These are the results.
